PICKER-STAFF CHECK FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 349,979, datedSeptember 28, 1886.

Application filed January 0, 1886. Serial No. 188,117. (No model.)

To all whom, it may concern.-

Be it known that I, BENJAMIN F. CARTER, a citizen of the United Statesof America, residing at Cleveland, in the county of Cuyahoga and Stateof Ohio, have invented certain new and useful Improvements in Picker-Staff Checks for Looms; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the ac companying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

This invent-ion relates to pickerstaff checks for looms; and it consistsin the construction and novel combination of parts, as will behereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a bottom view of a portion of a lay-beam ofa loom, showing the picking-stick in section and the pickerstaff checkin full lines in one position. Fig. 2 is a similar view showing thepicking-stick and the check in another position. Fig. 3 is a bottom viewof the picker-staff check detached. Fig. 4 is aside elevation oi'the pickerstaff check detached, the spring being shown in dotted lines; andFig. 5 is a transverse vertical sectional view of the check.

Referring by letter to the accompanying drawings, A designatesthclay-beain ofa loom, and B the slot therein at one end in which thepickerstaff works.

0 designates the picker-staff, the picker not being shown, it being ofany well-known construction.

D is a plate secured to the under face of the beam A by screws D D and Eis the latch, which is angular in form, having its end portion Fslightly curved, as shown, said end G terminating in a short arm, H. Thelatch E is pivoted at its inner end to the inner end ot the plate D onscrew D, and aspring, I, spiral in form, is interposed between the latchE and an upwardly-projecting shoulder, J, ris ing from the adjustableslide K, which latter is secured to the plate D by a set-screw, L,passed up through a slot, M, in the bottom of the plate D, and near itsouter end. By adjusting slide K the tension of the spring I is regulatedto cause it to exert greater or lesser resistance to the latch E, as maybe necessary in the use of the device. The latch E is normally at aninclined angle to the piekingstick, and checks the pickiugstick andprevents it from traveling to the end of the race, and holds said stickby friction until the stick is struck and driven back by the force ofthe shuttle, when it is sent from the opposite side of the race. In thisconstruction there is no tendency to rebound in the shuttle and nodanger of breaking the cops, which is of importance in running a loom,as with the check more force can be given to the shuttle in driving itwithout injury to the cop or rebounding of the shuttle.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

1. The combination, with the lay-beam of the loom, formed with the slotand the picking-stick therein, of the plate D, spring I, adjustableslide J K, latch E, and screws L and D, substantially as specified.

2. The combination, with the plate D and latch E, of the spring I,adjustable slide J K, and set-screw L,'substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

BENJAMIN F. CARTER.
